Title: Regulation of estrus and ovulation in gilts
Inventor: BURNS PATRICK J
IPC: A61K38/24
Filed: 1999-02-18
Abstract: Controlled release compositions and methods for inducing pseudopregnancy in gilts and sows are disclosed. In the preferred embodiment, the formulation includes polylactide microspheres releasing estradiol 17.beta. at physiologically useful levels over a period of time between five and thirty days. Following induction of pseudopregnancy, the pseudopregnancy can be terminated and estrus induced by administration of a compound such as PGF2.alpha.. The advantages of inducing pseudopregnancy followed by induction of estrus are that the breeding patterns of large numbers of gilts and sows can be controlled.

Abstract: A system and method for winding fibers onto an article is disclosed. The system includes a winding station having a controllable speed of rotation. The winding station has at least one fiber bobbin mounted on it. A rotation sensor is rotationally coupled to the winding station. The system includes a conveyor having a controllable speed and which is adapted to move the article axially through the winding station. A speed sensor, adapted to measure an axial speed of motion of the article through the winding station is positioned near the winding station. The system includes a controller adapted to operate the winding station at a rotational speed corresponding to the axial speed of motion, so as to apply the fibers to the article in a predetermined helical pattern. In one example, the helical pattern is held to a lay angle having a tolerance within one-half degree. In the method, the rotational speed of the winding station is adjusted to correspond to the axial motion of the article so that the fibers are wound in a predetermined helical pattern. In one example of the method, the lay angle of the fibers is held to within a tolerance of about one half degree. In another example, the lay angle is selected to correspond to the axial position of the article within the winding station.

IPC: A61K31/164
Filed: 1999-04-30
Abstract: Analogs related to oleamide are employed for potentiating the 5-HT2A and 5-HT1A responses to serotonin (5-HT). With respect to the potentiation of the 5-HT2A receptor response, it is disclosed that, of the naturally occurring fatty acids, the primary amide of oleic acid (oleamide) is the most effective potentiating agent of serotonin and that the potentiating activity of oleamide analogs is highly dependent upon their structural features. In particular, the presence, position, and stereochemistry of the 9- cis double bond is required and even subtle structural variations reduce or eliminate activity. Secondary or tertiary amides may replace the primary amide but follow a well-defined relationship requiring small amide substituents suggesting that the carboxamide serves as a hydrogen bond acceptor but not donor. Alternative modifications at the carboxamide as well as modifications of the methyl terminus of the hydrocarbon region spanning the carboxamide and double bond typically eliminate activity. With respect to the potentiation of the 5-HT1A  receptor response, it is disclosed that the potentiation activity of oleamide analogs is more tolerant and accommodates a wider range of structural modifications. One genus of analogs is disclosed that inhibits rather than potentiates the 5-HT2A, but not the 5-HT1A, receptor response. Such analogs permit the selective modulation of serotonin receptor subtypes and have opposing effects on the different subtypes.

Title: Optical data storage
Inventor: BURROUGHS TREVOR
IPC: G11B7/004
Filed: 1999-03-23
Abstract: The invention provides a high capacity three-dimensional, optically-addresse d storage device (1) comprising multiple juxtaposed storage layers (3, 4, 5) from which digital data stored in any given layer can be rapidly and reliabl y retrieved despite the presence of data stored in other layers and, in particular, the extreme proximity of data stored in neighbouring layers. In order to retrieve information stored in the device, interrogating radiation is projected through the device orthogonally to the layers, possibly in a flood  beam but preferably in a beam defined by means of an electronic mask, such a s a TFT array or a liquid crystal device. In any event, the interrogating beam  is repeatedly refocussed during its passage through the device to reduce retrieval errors associated with beam spreading. The given layer is selected  by illumination with a selecting beam of radiation projected across the laye r in question, to interact with optically sensitive material deposited at selected digital storage locations in the layer, so as to cause that materia l to absorb the radiation of the interrogating beam significantly more strongl y than it does in the absence of the radiation of the selecting beam.

Abstract: A system and method implemented in an interactive television system for managing modules of interactive television applications. The system transmits modules from a broadcast station to a plurality of receiving stations through various paths, such as broadcast channels and modem channels. The receiving stations have module managers which store module requests and which monitor the various channels for modules corresponding to the requests. When modules are transmitted on the monitored channels, they are matched with the corresponding stored requests. If a module matches one of the requests, or if it is an auto-loading module, it is stored in the receiving station. If a module has not been requested and is not an auto-loading module, it is ignored. The stored modules are added to a list of modules available for execution or for use by an executing application, and the corresponding requests are deleted.

Title: Instrumentation of calls to routines for which source code is unavailable
Inventor: MAXWELL SIDNEY R
IPC: G06F11/36
Filed: 2000-01-14
Abstract: A method and apparatus for testing and debugging a computer program that invokes one or more programming code modules not having source code available for instrumentation. A programming code module may be a function in a library provided by a third party, for example, that is invoked by a computer program.  The programmer indicates which programming code modules should be instrumented by directing the instrumenter to a header file that includes declaration statements for a specific set of programming code modules. A tagging instrumenter inserts a tagging variable assignment statement before and after each invocation of the selected programming code modules in the computer program's source code. The tagging instrumenter assigns a value to an entry tagging variable assignment statement equal to an entry code and a unique programming code module identifier. The tagging instrumenter assigns a value to an exit tagging variable assignment statement equal to an exit code and the unique programming code module identifier. The tagging instrumenter utilizes the same pair of values for each invocation of a given programming code module in the source code. During execution of the instrumented computer program, a probe captures the tagging variable assignment statement value pairs associated with each invocation of a programming code module. Analysis of the tagging variable assignment statement value pairs provides data related to the efficiency of each instrumented programming code module.
